This defaults to a pthread implementation but it can be switched over to a custom thread
handler if the frontend desires.

Ryan Houdek 83eb7f4ad3 Return EPERM in ptrace. A Feral launcher is attempting to use this to ensure it can't ptrace. 2021-03-31 23:37:56 -07:00
Ryan Houdek 4004d5a3b7 Disables seccomp 
FEX doesn't support seccomp in userspace and allowing these through causes chromium secure sandbox to break.
Disabling these with EINVAL allows FEX to behave as if seccomp isn't enabled in the kernel config

Necessary to get the Civ6 launcher further

Ryan Houdek 9b35cb4408 Returns EPERM on clone with namespace 
Notably this allows applications to work that don't require the namespace but check up front if they are able to clone with it.
Civ 6's launcher checks this as an example

Ryan Houdek 4ece56ac4d Fixes uname version string 
This wasn't following the correct format and it never actually had a working FEX_VERSION define.
Now it pulls in the GIT_DESCRIBE_STRING and brings in the correct date + time format

Scott Mansell 6ed36e3304 Refactor syscalls to take Frame 
The vast majoirty of syscalls don't need anything in thread or frame.
So lets save an indirection for all those syscalls.

Most of the syscalls which do need Thread (or CTX via
Thread are in Thread.cpp or Memory.cpp
These have all been modifiy to fetch Thread from Frame

Ryan Houdek a3ba1ae199 Deduplicates some configuration data 
Configuration mapping was duplicated between three different tables.
Additionally default configuration values were strewn about. Making it confusing as to what the default value would end up being

Adds a new ConfigValues.inl header that defines a few things right next to each other.
Defines the enum name as usual.
Defines the JSON config option name.
Defines the Environment config option name
Defines the default value that the configuration should be
